This product is amazing. It does not need to be refrigerated. It contains 14 strains of good bacteria (more than I have seen in any other animal probiotic). It is GMP certified. And, also very important, my dogs eat it up just fine. I have been buying this product for a very long time and I will not stop any time soon.

My dog's allergies have almost entirely cleared up after using this for 2 months (therapeutic dose of one scoop per day). I combined this with high quality dog food (Origen) and Udo's Choice powdered vitamins on a daily basis, and his scratching and scabbing have subsided considerably. For my 12lb Italian Greyhound, it lasts about a month to a month and a half. I have not tried any other, cheaper products, but this one did the job.
